Cyclosporin A is a cyclic peptide produced as a metabolite by the soil fungus Tolypocladium inflatum Gams. Cyclosporin A is immunosuppressive agent and effective to prevent rejection in oragn transplant patients.
Interactions
Cyclosporin A is known to interact with other drugs, the details of drug interactions is as follows:DrugDetailsSeverityOnsetManagementAceclofenacThe risk of nephrotoxicity increases when aceclofenac is used with cyclosporin.Afatinibcyclosporin may increase the level of afatinibuse alternative or reduced doseAliskirenAllopurinolAllopurinol possibly increases plasma concentration of ciclosporin (risk of nephrotoxicity).Amiloride (HCl)Amiodarone (HCl)Amiodarone may decrease the metabolism of CycloSPORINE by inhibition of CYP450 3A4 result in increase blood concentration of cyclosporin enhances the risk of nephrotoxicity and neurotoxicity. ModerateMonitor increased serum concentrations and/or toxicity of cyclosporine if amiodarone is initiated/dose increased, or decreased serum concentrations if amiodarone is discontinued/dose decreased. A reduction in cyclosporine dosage will likely be needed.AmobarbitalAmlodipine accelerates the metabolism of cyclosporin (reduced effects).AtazanavirAtazanavir possibly increases plasma concentration of Cyclosporin.AtorvastatinCyclosporin may increase the serum concentration of Atorvastatin. MajorMonitor altered effects (eg, increased serum CPK, myopathy, rhabdomyolysis) of Atorvastatin if Cyclosporin is introduced or discontinued, or when its dosage is modified.AzapropazoneAzithromycinMacrolides (e.g Azithromycin) possibly inhibit metabolism of Ciclosporin (increased plasma concentration).Benazepril (HCl)BosentanPlasma concentration of Bosentan increased by Cyclosporin (also plasma concentration of cyclosporin reduced -avoid concomitant use).Bromocriptine (Mesylate)CaptoprilCaptopril may enhance the nephrotoxic effect of CycloSPORINE.MajorDelayedMonitor for increased signs and symptoms of nephrotoxicity during concomitant therapy with cyclosporine and Captopril. Maintenance of adequate hydration (caution with diuretic use) may reduce of risk of ill effects.CarbamazepineCarbamazepine accelerates metabolism of Cyclosporin (reduced plasma concentration)due to hepatic metabolism induction.MajorBetter to avoid this combination or monitor serum concentration of cyclosporine.CelecoxibCerivastatin SodiumChloroquineCimetidine (HCl)Cimetidine competitively inhibits creatinine clearance for renal tubular secretion,increases serum creatinine and may antagonize cyclosporine-induced inhibition of interleukin-2 production in patients treated with cyclosporine.MinorRanitidine may be preferable to cimetidine in patients using cyclosporine.CinoxacinCiprofloxacinCiprofloxacin increases the serum concentration of cyclosporin. The risk of cyclosporine induced neurotoxicity and nephrotoxicity may also be increased.ModerateCyclosporine levels and renal function must be closely monitored.CisaprideCyclosporin increases the plasma concentration of cisapride by inhibiting its metabolic clearence.Increased level of cisapide results in prolongation of QT interval on ECG, ventricular arrythmia, cardiac arrest and sudden death.MajorCoadministration should be avoided.ClarithromycinCyclosporin enhances the blood concentration of clarithromycin by inhibiting hepatic and intestinal metabolism result in increased risk of nephrotoxicity and neurotoxicity.ModerateCoadministration of these agents should be avoided. Blood level of cyclosporin and renal function should be checked frequently. Adjust the dose accordingly.Patient should notify their physician if experience nausea, vomiting, diarrhea, abdominal pain, dizziness, fatigue, or headache.ColchicineCo-TrimoxazoleDanazolDanazol can increase plasma concentration of cyclosporinDexibuprofenDiclofenac (K)Diclofenac (Na)nephrotoxity may occurDigoxinCycloSPORINE may decrease the metabolism of Digoxin.ModerateRapidMonitor for toxic effects of Digoxin if cyclosporine is initiated/dose increased, or decreased effects if cyclosporine is discontinued/dose decreased. Diltiazem (HCl)DocetaxelEnalapril (Maleate)ErythromycinErythromycin by interfering in hepatic and intestinal metabolism increases blood concentration of cyclosporine through CYP450 3A4 inhibition and may result in nephrotoxicity and neurotoxicity.ModerateGenerally avoid.Adjust dose and check cyclosporine blood levels and renal function.Estradiol (Valerate)EthylestrenolEthynodiol (Diacetate)EtodolacFenbufenFenoprofenFloctafenineFluconazoleHigh doses(more than 200 mg per day) of fluconazole can increase serum concentration and toxicity of cyclosporine through CYP450 3A4 hepatic and or gut wall metabolism inhibition.Moderatedose adjustmnet and monitoring of renal function and serum cyclosporine levels are required.FlurbiprofenRisk of nephrotoxicity increases if given with cyclosporin.Fluticasone PropionateFoscarnet (Na)FosphenytoinGallopamilGentamicinIndomethacinIndomethacin exacerbate the nephrotoxic effect of cyclosporin.ModerateClosely monitor for renal functions.ItraconazoleItraconazoleKetoconazoleKetoconazoleKetoprofenLevofloxacinConcomitant use of levofloxacin and cyclosporin increases nephrotoxicity.LovastatinMeclofenamic AcidMeloxicamMelphalanMethylprednisoloneMethylprednisoloneConcomitant use can lead to convulsionsMethyltestosteroneCoadministration with androgens or anabolic steroids may increase the blood concentrations of cyclosporine. The exact mechanism of interaction is unknown but may involve competitive inhibition of the CYP450 3A4 metabolism of cyclosporine. There have been case reports of transplant patients who developed cyclosporine toxicity following the addition of methyltestosterone or danazol. In addition, a pharmacokinetic study in one patient found that cyclosporine systemic exposure (AUC) increased 65% during coadministration with danazol, despite a reduction in cyclosporine dose. The interaction has not been reported with other androgens or anabolic steroids but may theoretically occur due to the structural similarities of these agents. Pharmacodynamically, there is also a potential for additive hepatotoxicity during coadministration, as both cyclosporine and androgens can have adverse effects on the liver.ModerateCaution is advised if cyclosporine is prescribed with androgens or anabolic steroids. Cyclosporine blood levels, renal function, and liver function tests should be monitored frequently and the dosage adjusted accordingly, particularly following initiation, discontinuation or change of androgen dosage in patients who are stabilized on their cyclosporine regimen. Patients should be advised to notify their physician if they experience possible signs of cyclosporine toxicity such as nausea, vomiting, diarrhea, abdominal pain, dizziness, fatigue, headache, tremors, and convulsions.Metoclopramide (HCl)Metoclopramide increases the bioavailability of cyclosporinby increasing gastric emptying and may interfere with gastrointestinal degradation of cyclosporin, thus increases the risk of toxicity.ModerateCarefully monitor cyclosporin level, renal function and serum creatinine level of patient.MetolazoneMibefradil (Di HCl)Mitozantrone (HCl)MizolastineConcurrent use may increase the blood level of mizolastine and could increase the risk of side effects.ModafinilConcurrent use may decrease the effectiveness of modafinil.Mumps VaccineConcurrent use may weaken the immune system.Muromonab-cd3Likely interaction of MUROMONAB CD3 increasing the SERUM LEVEL of CYCLOSPORIN.
